Solution Overview

Problem

Information handling systems face challenges in quickly recovering from cyber attacks and boot device corruption, as existing boot processes do not account for compromised devices and can lead to prolonged downtime and performance issues.

Innovation Solution

The implementation of an information handling system firmware (IHSFW) that determines issues with the primary boot device, stores event logs, and automatically fails over to a hidden recovery boot device, making it visible and booting from it to minimize downtime and ensure system recovery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system boots from the primary boot device, then normal operation is maintained, but if the primary boot device is compromised or corrupted, the system experiences prolonged downtime and cannot recover quickly

Engineering Contradiction:
Improvesystem recovery capabilityVSAvoiddowntime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

A recovery boot device is pre-configured and prepared in advance with necessary recovery operating systems and tools. This preliminary action ensures that when the primary boot device is compromised, the system can immediately switch to the pre-prepared recovery device without time-consuming setup or configuration, thereby reducing downtime while maintaining reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The firmware acts as an intermediary between the primary boot device and the recovery boot device. It monitors the boot process, detects issues with the primary device, and automatically transitions to the recovery device. This intermediary mechanism enables seamless failover, preventing prolonged downtime while ensuring the system can recover from primary device failures

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If a recovery boot device is made visible and accessible, then system recovery can proceed, but security risks may increase from unauthorized access

Engineering Contradiction:
Improverecovery accessibilityVSAvoidsecurity risk
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The recovery boot device is assigned a distinct, localized configuration that differentiates it from the primary boot device. This includes specific identifiers, access controls, and operational characteristics that limit its functionality to recovery operations only. This local quality approach enables easy recovery access while preventing unauthorized use for other purposes, thus balancing accessibility with security

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The potential security risk of having an accessible recovery device is converted into a benefit by implementing controlled accessibility. The recovery device's visibility and access mechanisms are designed to be useful for authorized recovery operations while inherently preventing unauthorized access through architectural constraints. The apparent vulnerability becomes a feature that enables rapid recovery when needed

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

In one or more embodiments, one or more methods, processes, and/or systems may modify a configuration of an information handling system (IHS) to prevent access of a first non-volatile memory medium, associated with the IHS, that stores a recovery operating system; may boot the information handling system from a second non-volatile memory medium of the IHS; may determine that at least one issue associated with a boot sequence has occurred; may modify the configuration of the IHS to provide access of the first non-volatile memory medium; may modify the configuration of the IHS to boot the information handling system from the first non-volatile memory medium; may restart the IHS; and may boot the recovery operating system from the first non-volatile memory medium.
